To increase the range of dipped headlights a new form of auxilliary headlamp has been developed under the name of "motorway dipped light"; this lamp produces twice as wide a band of light on the right hand side of the carriageway compared to the usual halogen dipped light. The width of view on the right hand carriageway side is increased by nearly 100%, and the dazzle value on the left hand side is increased only marginally above that of the usual dipped light. The new lamps have not yet been approved. - to adapt the headlamp to the loading condition of a vehicle, an automatic beam width regulator has been developed, which operates more securely, more precisely and faster than headlamps, which need to be adjusted by hand. In certain articulated vehicles, for example, these electronic beam width regulators have already been introduced on a series-production basis. - to reduce the braking time when driving in platoons auxilliary high positioned braking lights are recommended. Whilst the ordinary brake light can only be seen by the following vehicle driver, high set lights can be seen by virtually all the successive drivers in the platoon at the same time. From research it is suggested that the lamps be fitted at a height of 125 cm. It is appropriate to mount the lamps on the rear window. Formal approval for these auxilliary lamps has not yet been received. (TRRL)
